Answer:
a.Resistance of bulb==192 ohm
b.power consumed by bulb after motor disconnection=74.609 W
Explanation:
<u>a.Resistance of bulb=</u><u>=?</u>
As we know that
putting R as resistance of bulb i.e.
<u>b.power consumed by bulb after motor disconnection? </u>
from the figure we see that are in series so
current through their resistance is
Power consumed by bulb is
Answer:
a
The current that would be produced is
b
Yes this arrangement can be used to cancel out earths magnetic field at points well above the Earth's surface.This is because this current loop acts as a magnetic dipole for point above the earth surface
c
No this arrangement can not be used to cancel out earths magnetic field at points on the Earth's surface .this because on the earth surface it shifts from its behavior as a magnetic dipole
Explanation:
From the question we are told that
The magnetic moment of earth is
The radius of earth generally has a value of
Magnetic moment is mathematically given as
A is the area of the of the earth(assumption that the earth is circular ) and this evaluated as
Now making the subject in the above formula
